Handheld apps that work by touch require you to design not only how your pixels look, but how they *feel* in the hand. What are the ergonomic challenges and interface opportunities for designing mobile touchscreen apps?

In his half-day workshop on “Designing for Touch,”Josh Clark (author of “Tapworthy: Designing Great iPhone Apps”) will explore how fingers and thumbs turn desktop conventions on their heads, requiring you to leave behind familiar design patterns. The workshop presents nitty-gritty “rule of thumb” design techniques that together form a framework for crafting finger-friendly interface metaphors, affordances, and gestures for a new generation of mobile apps that inform and delight.
